Title: litecoin cgminer Post by: avirdoz on September 24, 2012, 12:17:03 AM Hello. I try to mine litecoin with cgminer (v. 2.7.5, xubuntu 12.04, sdk 2.7). But when i try to start it:
Code: ./cgminer --scrypt -o xxx -u xxx -p xxx Thx.

Just check you have the needed dependencies :) I prefer to build the miner on my own hardware also - it helps ensure I know what the code is doing and that it's optimised for what it's running on.

Some info about my rig:
Xubuntu Live (on 4 gb flash usb); 4 GB RAM; HD 6950 unlocked @6970; HD 6970 I build cgminer with --enable-cpumining & --enable-scrypt. When i start cgminer i receive error message: Code:
Without --thread-concurrency option maximum hashrate about 340 on each gpu khash/s. Title: Re: litecoin cgminer Post by: SAC on October 03, 2012, 05:49:46 PM Hello again.

Without --thread-concurrency option maximum hashrate about 340 on each gpu khash/s. Try something like I used in a machine with two 6950s flashed to 70s. Code:
And the card speeds. Code:
This gives me 410kh/s per card, leave out the --shaders like I do only one of them is needed so it is it or the --thread-concurrency option not both.

Title: Re: litecoin cgminer Post by: SAC on October 03, 2012, 07:51:37 PM I try with your confgs. 313 khash/s per device. Why you decrease stock engine and memory clocks? Through many hours of messing about one day those are the settings I found give me the max hash rate possible. I did this on every card I have and every one without exception gives more hashes if you lower the gpu engine below stock speeds and raise the memory speed once you get to a certain point on the memory nothing above it will give you more speed in fact usually decreases it.

No it automatically manages the gpu engine if it gets above the --temp-target you set the --auto-fan does the fan speed to keep it below the --temp-target. The second set of my posting is the speed settings I set for ltc mining the --od-setclocks lines.

AMD-APP-SDK-v2.7-RC-lnx64 is the directory I get from the tarball I downloaded and fglrx_8.980-0ubuntu1_amd64.deb is the package that was built from the .run file I downloaded I think the 12.6 version. You want to check the proper speeds are being set in my experience with cgminer unless you set them manually then it will use whatever is programmed in the cards BIOS ignoring the values put into your .cgminer.conf. You do this by using. Code: DISPLAY=:0 aticonfig --od-enable --adapter=all In a terminal/console window. Title: Re: litecoin cgminer Post by: SaintDevil on October 18, 2012, 10:35:05 AM Hello again.

You will get this error message if your thread-concurrency is set high but the memory clock on the graphics card is under clocked. I've ran into this problem while trying to mine litecoins, then I restored my graphics card settings back to original and it started hashing without problem.
